Kudos to the folks at Slideshare who have created a new way to share presentations online. Your voice can now be added to your presentations. I haven't had a chance to play with this feature yet—but essentially it looks like you upload an audio file to a previously uploaded presentation and you "splice" the audio to sync up with your slides.
I think this shakes up how thought leadership gets created, produced, shared and distributed. My one recommendation to the folks at Slideshare? Figure out how to do simple transitions. Even fades, which give the illusion of passing time can be helpful in a presentation as you narrate with visuals.
This experience will never replace actually "being there" or even the power of video. But like blogging and text, it makes it easy for unknown voices to be heard (take it from me). And if you have a voice—and a good story to go with it, then this tool might just be for you.
